Case Converter

What is a Case Converter?

A Case Converter is a text transformation tool that changes the capitalization of letters in your text. Different programming languages and writing styles require different case conventions, making case conversion an essential utility for developers and writers.

Common case styles include:

  • UPPERCASE: All letters in capital (e.g., HELLO WORLD)
  • lowercase: All letters in small case (e.g., hello world)
  • Title Case: First letter of each word capitalized (e.g., Hello World)
  • camelCase: First word lowercase, subsequent words capitalized (e.g., helloWorld)
  • snake_case: Words separated by underscores, all lowercase (e.g., hello_world)

Case converters are essential for developers working with different naming conventions across programming languages, for writers formatting titles and headings, and for anyone who needs to quickly transform text to match specific style requirements. Each case style serves different purposes in code readability, API design, and document formatting.
